New researches in hybrid alkaline metakaolin-waste glass cements is being
developed in search of a new generation of binders. Attempts to reduce its CO2
footprint by blending Ordinary Portland Cement with pozzolanic materials, such
as fly ash, blast furnace slag or metakaolin [1], have yielded pozzolanic cements
with technical properties comparable to those of ordinary cement [2]. In alkaliactivated
cementing, drying shrinkage is higher than that of ordinary
cementitious materials, but restrained shrinkage is lower due to lower modulus
of elasticity.
This paper reports the compressive strength and microstructure characteristic
of hybrid alkaline metakaolin-waste glass cements and cement under curing
methods. metakaolin and waste glass were used to replace part of Portland
cement as mass of binder.
